Method for assessing reverse antenna feeder between cells of base stations

Abstract

The invention discloses a method for assessing reverse antenna feeder between cells of a base stations. The method is characterized by: firstly, collecting switching measurement data in telephone traffic statistics and analyzing; then, according to an azimuthal angle of the cell, the azimuthal angle of the neighbor cell, an included angle formed by a line between the cell base station and the neighbor cell base station and a cell covering direction, and the included angle formed by the line between the cell base station and the neighbor cell base station and a neighbor cell covering direction, classifying the base stations and the neighbor cell; finally, assessing the cells with the reverse antenna feeder according to a relationship between various neighbor cell switching time ratios and a setting value. In the method of the invention, through using the switching measurement data in the GSM telephone traffic statistics and according to the various neighbor cell switching time ratios, whether there is the reverse antenna feeder in the cells can be determined, simultaneously, correctness of engineering parameters (latitude and longitude, the azimuthal angle and the like) can be determined. Checking efficiency of whole network engineering quality can be effectively raised. Network quality can be improved and assessment costs can be reduced at a certain degree.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for evaluating reverse connection of antenna feeder lines between base station cells in a mobile network. Background technique [0002] With the development of mobile communication networks, the mobile network scale of mobile communication operators is getting larger and larger, and the network structure is becoming more and more complex. How to optimize the mobile communication network in a real-time, comprehensive, effective, fast and timely manner is becoming more and more important. [0003] The transmission of signals by the wireless base station and the reception of the signals transmitted by the mobile station are completed through the antenna feeder system (the antenna feeder system refers to the antenna radiating electromagnetic waves to the surrounding space), so the installation quality and operation of the antenna feeder system will directly affect To call...
